In the figure, the inner (shaded) region A represents a sphere of radius $$r_A = 1$$, within which the electrostatic charge density varies with the radial distance $$r$$ from the center as $$\rho_A = kr$$, where $$k$$ is positive. In the spherical shell B of outer radius $$r_B$$, the electrostatic charge density varies as $$\rho_B = \dfrac{2k}{r}$$. Assume that dimensions are taken care of. All physical quantities are in their SI units.

Which of the following statement(s) is(are) correct?
